Abstract
Description
【発明の詳細な説明】 プラズマトーチ内の電極消耗 本発明は、炭化水素の処理及び分解においてプラズマトーチ内の電極消耗を減少 させるための方法に関する。[Detailed description of the invention] Electrode wear in plasma torch The present invention reduces electrode wear in plasma torches in hydrocarbon processing and decomposition. Concerning a method for doing so.
プラズマトーチ内での天然ガスの処理及び分解の際には、電極の消耗が起こり、 その結果、使用期間後にこれらを補充するか又は取り替える必要が生じる。この 消耗は、高価な電極材料の消耗に加えて、前記処理の操業停止を引き起こし、そ の結果、時間が浪費され得るため、そして生産が中断されるため、好ましくない 。During the processing and decomposition of natural gas in a plasma torch, electrode wear occurs and As a result, they need to be replenished or replaced after a period of use. this Attrition, in addition to the consumption of expensive electrode materials, can cause shutdowns of the process and undesirable because it can result in wasted time and production interruptions. .
これに代わる方法の一つとしては、連続的に補充されることができ、分解生成物 を汚染しないグラファイト又は炭質材料製の再生可能電極を使用することであっ た。これは、生成物を汚染するだけでなく、より複雑且つより高価な非消耗電極 の使用よりは安価になる。One alternative to this is that it can be continuously replenished and decomposition products By using renewable electrodes made of graphite or carbonaceous materials that do not contaminate Ta. This not only contaminates the product, but also requires more complex and more expensive non-consumable electrodes. It is cheaper than using .
本発明の目的は、電極が再生可能な電極からなるか、消耗され得る電極からなる かにかかわらず、炭化水素の分解及び処理のためのプラズマトーチ内の電極材料 を減少させるための方法を提供することにある。It is an object of the invention that the electrodes consist of renewable electrodes or consist of consumable electrodes. Electrode materials in plasma torches for the decomposition and treatment of hydrocarbons, whether The objective is to provide a method for reducing the
この目的は、提出した特許請求の範囲に示した特徴により特徴付けられる方法に より達成される。This object is directed to a method characterized by the features indicated in the filed claims. more achieved.
トーチ内で分解されるべき炭化水素が、実際のプラズマガスにそれらを混入する ことにより、電極消耗を減少させるために使用され得るという驚くべき発見がな された。炭化水素を直接にプラズマガスに添加することにより、前者は、電極消 耗が起こる実際のフレームゾーン中で、水素とカーボンブラックとに分解され、 生じたカーボンブラックは、消耗が起こるのと同じ領域に付着する。このように して、完全に又は部分的に消耗を補い得る電極の生長が得られ、これにより、電 極の寿命が明らかに延びる。Hydrocarbons to be decomposed in the torch mix them into the actual plasma gas A surprising discovery has been made that it can be used to reduce electrode wear. It was done. By adding hydrocarbons directly to the plasma gas, the former eliminates electrode consumption. In the actual frame zone where wear occurs, it is decomposed into hydrogen and carbon black, The resulting carbon black deposits in the same areas where depletion occurs. in this way This results in electrode growth that can fully or partially compensate for wear, thereby increasing the The life of the poles is clearly extended.
例えば、メタンである炭化水素の混合量を、そして可能であればガスの導入領域 及びその温度を調節することにより、電極への付着を調節し、そしてこれにより この好ましい効果を得ることも可能になる。For example, the amount of the hydrocarbon mixture, which is methane, and if possible the introduction area of the gas. and its adhesion to the electrode by adjusting its temperature, and thereby It also becomes possible to obtain this favorable effect.
この様に電極上の「汚れ」を有利な効果として利用することは、非常に驚くべき ことである。今まで、プラズマトーチの操作における最も大きな問題の一つは、 正にこの、分解中に生じる電極上の汚れであった。It is very surprising that "dirt" on the electrode can be used as an advantageous effect in this way. That's true. Until now, one of the biggest problems in the operation of plasma torches is This was exactly the stain on the electrode that was generated during decomposition.
しかしながら、本発明に従って遂行すると、この汚れの影響が、天然ガスを実際 のプラズマガスと混合することにより調節され、所望の領域に導かれるのである 。従って、入手が容易でリーズナブルな価格の天然ガスが用いられるので、高価 な手段に頼る必要なしに、電極の寿命が延び得る。プラズマガスの組成に後成長 （ａｆｔｅｒ−ｇｒｏｗｔｈ）による変化が生じないことを確実にするために、 プラズマガスとして前ちって水素を使用すると、特に好ましい効果が得られる。However, when carried out in accordance with the present invention, this fouling effect effectively reduces natural gas It is controlled by mixing with the plasma gas and guided to the desired area. . Therefore, natural gas, which is easy to obtain and reasonably priced, is used, making it expensive. The life of the electrode can be extended without having to resort to advanced measures. Post-growth due to plasma gas composition To ensure that no changes occur due to (after-growth), Particularly favorable effects are obtained if hydrogen is used upfront as plasma gas.
銅電極及びグラファイト電極の両方を用いて試験を行ったところ、いずれの型の 電極についても同じ効果が得られた。出願人自身の実験により得られた効果を図 中に示すが、これは、水素プラズマガスと混合されるメタンの量（％）の関数と しての電極の消耗を示す。Tests were conducted using both copper and graphite electrodes, and both types The same effect was obtained with electrodes. The figure shows the effects obtained through the applicant's own experiments. This is a function of the amount (%) of methane mixed with the hydrogen plasma gas. This shows the wear of the electrode.
このように、本発明の簡単な方法により、プラズマトーチの操作において著しい 改良がなされた。得られるもう一つの利益は、炭化水素ガスの混合により、電極 上の熱負荷を減少し得ることであり、この効果は、プラズマガスとして水素を用 いた場合に特に顕著である。Thus, the simple method of the present invention provides significant improvements in the operation of plasma torches. Improvements have been made. Another benefit obtained is that by mixing hydrocarbon gases, the electrode This effect can be achieved by using hydrogen as the plasma gas. This is especially noticeable when
従って、炭化水素ガスからの純粋な分解生成物の製造のための炭素電極の場合に おける電極消耗は、本発明により、プラズマガスへの炭化水素ガスの、誘導され 且つ調節された混合により、部分的に又は完全に減少し得る。電極の生長を消耗 点で調節することを可能にするために、天然ガスの混合量を、プラズマトーチの アーク電圧に基づいて計算された調節パラメーターに基づいて適切に調整するこ とができる。Therefore, in the case of carbon electrodes for the production of pure decomposition products from hydrocarbon gases According to the present invention, electrode wear due to the induction of hydrocarbon gas into the plasma gas And by controlled mixing it can be partially or completely reduced. Consuming electrode growth In order to be able to adjust the amount of natural gas mixed in the plasma torch, Proper adjustment based on adjustment parameters calculated based on arc voltage. I can do it.
